PR Comment Handler

Guide to find the open PR for the current branch and address its comments with gh CLI. Run all gh commands with elevated network access.

Prereq: ensure gh is authenticated (for example, run gh auth login once), then run gh auth status with escalated permissions (include workflow/repo scopes) so gh commands succeed. If sandboxing blocks gh auth status, rerun it with sandbox_permissions=require_escalated.

1) Inspect comments needing attention

• Run scripts/fetch_comments.py which will print out all the comments and review threads on the PR

2) Ask the user for clarification

• Number all the review threads and comments and provide a short summary of what would be required to apply a fix for it
• Ask the user which numbered comments should be addressed

3) If user chooses comments

• Apply fixes for the selected comments

Notes: - If gh hits auth/rate issues mid-run, prompt the user to re-authenticate with gh auth login, then retry.
